CS111: Data Types - Strings

Using strings for character names, sprite paths, and game states

Data Types: Strings

Objective

Students must use string data types to store and manipulate text data in the game.

Evidence

String usage in game components:

GameLevelOutside.js - Character names, sprite paths
GameLevelMaze.js - Level identifiers and state strings
Multiple classes - NPC dialogue and game messages

Implementation Details

String literals with single and double quotes
Template literals for string interpolation
String methods for manipulation
String comparisons for game logic
Path construction and concatenation

Key Concepts

String primitives vs String objects
String methods (indexOf, substring, split, join, replace, etc.)
Template literals with ${} interpolation
String immutability in JavaScript
Regular expressions for pattern matching
